Babel Plugin to transform method chaining to react-addons-update format.

On purpose support manipulating presist data with method chaining.

TODO

Replace deep clone. No need to change a lot codes.

Add in your package.json

"devDependencies": {

  ...

  "babel-plugin-gr-assign": "[email protected]:poiyzy/grAssign.git"
},

npm install

支持将 $_grAssign = a.b.c.d = 2; 转换为:

$_grAssign = grUpdate(a, {
  b: {
    c: {
      d: {
        $set: 2
      }
    }
  }
});

关于 react-addons-udpate

TODO

    plugins: [
      [grAssign, {
        alias: '$_g',
        method: 'update'
      }]
    ]

• alias: 设置 variable 别名，默认为 $_grAssign
• method: 设置 update 方法别名，默认为 grUpdate

使用 a[{index}] 或 a[[index]] 来标记 数组 index.

var $_grAssign;
var a = { b: [{name: 1}, {name: 2}, {name: 3}] }

let index = a.b.findIndex(function(e) { return e.name === 2 });

$_grAssign = a.b[{index}].name.set('test');

会转化为：

$_grAssign = grUpdate(a, {
  b: {
    [index]: {
      name: {
        $set: 'test'
      }
    }
  }
});

• Assign

  $_grAssign = a.b.c = 3;

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $set: 3
        }
      }
    });

• $set

  $_grAssign = a.b.c.set(3);

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $set: 3
        }
      }
    });

• $push

  $_grAssign = a.b.c.push(3);

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $push: [3]
        }
      }
    });

• $merge

  $_grAssign = a.b.c.merge(3);

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $merge: [3]
        }
      }
    });

• $splice

  $_grAssign = a.b.c.splice(1, 2, 3, 4);

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $splice: [[1, 2, 3, 4]]
        }
      }
    });

• $apply

  $_grAssign = a.b.c.apply(function(e) { return e; });

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $apply: function(e) { return e; }
        }
      }
    });

• $unshift

  $_grAssign = a.b.c.unshift(1);

  转换为

    $_grAssign = grUpdate(a, {
      b: {
        c: {
          $unshift: [1]
        }
      }
    });
